The Texas Terror began playing in 1996, which is when arena football first entered my sphere of interest. They were later rechristened the ThunderBears which I always thought was stooopid.

Additionally, Houston had at one point an INDOOR soccer team, which was AWESOME. It was soccer played on a pitch roughly the size of a basketball court. It was played in the same arena, the Summit, that the Rockets played in. I LOVED indoor soccer, I think I watched every HotShots game that was televised.
